Six monitoring committee members of a company that operated a common effluent treatment plant in an industrial estate in Ranipet have been arrested in connection with the January 31 death of ten tannery workers, who drowned in sludge from the plant following a wall breach.

West Bengal Chief Minister Mamata Banerjee announced a compensation of Rs two lakh to the next of kin of the nine labourers of the state, who were killed when an effluent tank at a tannery in Vellore collapsed, a senior police officer said on Saturday.
